Nice-to-haves (there's a lot):

• Current cmd / matrix / address states (cmds mostly done.)
• Current depthbuffer / stencil from framebuffer.
• Other framebuffers (when cached / collected?)
• Current display buffer (to see when it flips) - nah, doesn't seem useful.
• Other textures (when cached / collected?)
• Disable caches (vertex, texture.)
• Visualize vertexes (red overlay, bounds, something?)
• Break on next list execution.
• Break on the usage of a texture.
• Break on next frame.
• Break on particular cmd change.
• Break on vertex bounding box.
• Break on signal / call / ret / etc.?
• Break on block transfer?
• Kill displaylist.
• Skip / force jump in displaylist (e.g. set pc.)
• Modify list ops.
• Modify cmd state? Could just ExecuteOp()? (could be improved.)
• Conditional breaks (e.g. only when vtype matches morph mask)? Could get really hairy.

User interface ideas:

• Lots of state. Maybe watch certain values (can also set breaks), and have an "all" tab?
• Perhaps top-level tabs: "Drawing" (current list, state, framebuffer), "Framebuffers", "Textures", "Lists" (possibly? to see other lists...), "Matrices".
• Thinking top-level tabs on top, renderbuffer right below that, list panel on the left, state panel on the right (might have tabs itself.)
